Product Description:
The MHD112B-058-NG0-BN is a three-phase servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a rotary actuator, it converts drive current into closed-loop motion for axis control on packaging lines, gantry stages, and similar automated machinery. Its permanent-magnet rotor and digital feedback system help the controller maintain commanded speed and position when load conditions change. This supports repeatable motion in multi-axis equipment where precise synchronization and stable response are required.
At standstill, the motor provides 28.0 Nm of continuous torque, enough to hold or index loads without overheating during normal continuous-duty operation. The housing has an IP65 protection class, which keeps out dust and low-pressure water jets during machine-side installation. Cooling is handled by liquid cooling, with coolant circulated through the stator jacket to remove heat and support sustained output. The motor uses a 192 mm square flange for mounting, and an optical digital encoder supplies position data with a closed-loop accuracy of ± 0.5 angular minutes. It comes without a holding brake, and its plain shaft with an internal shaft seal is intended for external couplings while helping protect the bearings. The motor also uses Class F insulation, and winding code 058 identifies the electrical characteristics expected by the matching drive.
A 130 mm centering diameter locates the housing precisely on the machine interface, and supply conductors enter through an output connector on side B to keep cable routing compact. Continuous duty is permitted in ambient temperatures from 0 to 40 °C, while storage is allowed from -20 to +80 °C when the motor is not operating. Installations up to 1000 m above MSL require no derating. Relative position detection is provided by the HSF optical encoder, and the motor uses size 112 with length code B. The design also includes a plain shaft with a positive seal.
